1'0 (tZZ whom it may concern.-

Be it known that I, THOMAS HANLON, a citizen of the United States,residing at Omaha, in the county of Douglas and State of N ebraska, haveinvented a new and useful Concrete-Constructor, of which the followingis a specification.

My invention relates to concrete constructors or molds designedespecially for use in producing concrete, cement, or otherartificial-stone walls in building construction or the like, and has forits objects to provide a simple inexpensive device of this character inwhich the retaining plates or members constituting the walls of the moldmay be readily released from and advanced along the course of the wallas the construction of the latter progresses, thereby insuring acontinuous operation in the formation of the wall, one in which theretaining-plates in moving to casting position will be limited in saidmovement when in proper parallel relation, and,

one in which said members may be readily adjusted toward and from eachother for varying the thickness of the wall and be securely lockedagainst movement during the molding operation.

To these ends the invention comprises the novel features of constructionand combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of thesupporting and operating mechanism for the mold members. Fig. 2 is asectional elevation illustrating the retainer-plates in position and thedevice in the operation of constructing a wall. Fig. 3 is a perspectiveview of one of the hangers. Fig. 4 is a similar view of one of theactuating-links. Fig. 5 is a detail perspective View of one of theadjustable sections of the supporting bar or member.

In the construction of cement, concrete, or other artificial-stonewalls, curbs, and the like it is customary to employ a pair of parallelretaining plates or members constituting the walls of the mold andbetween which the material is cast, the retainer members being from timeto time advanced along the course of the wall as the formation of thelatter progresses, thus providing for a continuous operation in theconstruction of the wall. It is the primary purpose of this invention toprovide a simple and efiicient mechanism for sustaining and manipulatingthe retainer members and for readily advancing the latter.

In accordance with my invention the retaining plates or members 13 aresustained by hangers 9 10, connected in turn to a supporting bar orframe comprising a pair of parallel spaced plates or embers '1 and 2,having a series of alined coincident perforations 3, suitably spaced ina direction longitudinally of the plates and adapted for the receptionof connecting bolts or devices, as hereinafter explained.

The supporting bar or frame, which normally lies in a horizontal plane,is provided at its opposite ends with longitudinally-adjustablesections, each comprising a pair of plates 4 5, carried, respectively,by the spaced plates 1 2 and having perforations 6, adapted to registerwith the perforations 3, for the reception of bolts or other fasteningmembers by which the adjustable sections are connected with thesupporting-bar. These sections, which carry, respectively, the hangers 910 and are adjustable for varying the distance between the latter, areprovided with a plumblevel support in the form of inturned longitudinalflanges 8, formed upon the plates 5, whereby a level may be readilyemployed for bringing the supporting-frame to the proper horizontalposition.

Pivoted, respectively, to and between the plates 4: 5 of the adjustablesupportingsections is a pair of hangers 9 10, formed, preferably, fromplate metal angularly bent to produce on each an inner front wall orportion 11 and an outwardly-projecting side wall or portion 14,saidhangers being provided at their lower ends with engaging devices orseats consisting of inwardly-upturned hooks 12, designed for engagementwith the lower edges of the retaining plates or members 13, the upperends of the side portions 14 being extended above the adjacent ends ofthe front portions 11, thus producing stops or abutments 14: for apurpose which will hereinafter appear.

The upper projecting ends of the hangers are pivoted, as at 15, betweenthe plates 1 5 of the adjustable sections, thus permitting of thehangers swinging toward and from each other in moving the mold-walls toand from casting position, this swinging movement of the hangers beingeffected by an actuating mechanism comprising a pair of operatinglevers21 22 and two pairs or sets of togglelinks, disposed, respectively, atopposite ends of the supporting bar or frame. toggle-links comprises aprimary link 17, pivoted between its ends to the outer end of theadjacent adjustablesection of the supportingbar for its upper end toproject, as at 20, above the latterJand a secondary link 16, pivoted atits lower end to the lower end of the portion 14 of the hanger, thelinks being in turn pivotally connected, as at 19. Formed in the portion1 1 of each hanger is a seat or recess 17, designed for the reception ofthe adjacent end of the primary link 17, whereby when theoperating-levers are manipulated for bringing the retaining-plates 13 tocasting position the links 16 17 will move into parallel relation withthe lower end of the link 17, engaging the hangers for locking thelatter against outward movement, inward move ment of the hangers beingprevented, owing to engagement of the stops or abutments 14 with theadjacent lower edge of the plate 1, whereby the hangers will bemaintained in vertical parallel position and the retainers 13 inparallel relation.

The operating-levers 21 22 are crossed adjacent to their longitudinalcenters and pivotally connected by means of a bolt or its equivalent 23,the ends of the levers being pivotally connected, respectively, with theupper projecting ends 20 of the primary links 17, whereby as the mainoperating-lever 21,

which is provided at its free end with a suitable handle 24, is swungvertically upward the toggle-links will be caused to break joint at thepivots 19, thereby swinging the hangers from each other and disengagingthe retainers 13 from the adjacent faces of the wall. When in castingposition, the levers 21 22 will lie in parallelism in a horizontal planeand may be locked against movement for securely holding the walls of themold in casting position by means of bolts 26, inserted throughregistering openings 25, provided in the levers upon opposite sides ofthe pivot 23.

In practice it is contemplated to employ one of the sustaining andoperating mechanisms at each end of the mold and as many mechanismsbetween the ends as may be necessary for properly supporting themoldwalls. Furthermore, under certain conditions, such as in theconstruction of subwalls and in order to utilize the previously-constructed main wall as one side of the mold, I propose to detach one ofthe hangers, together with its operating-lever and toggles, and connectthe adjacent end of the support Each set of A ing-frame directly to themain wall by means of a vertical bar or other connecting member attachedto the wall.

From the foregoing it is apparent that I produce a simple efficientdevice admirably adapted for the attainment of the ends in view, itbeing understood that minor changes may be made in the details hereinset forth without departing from the spirit of the invention.

Having thus described my invention, what I claim is- 1. The combinationwith a support, of notched hangers carried by the support and linksconnected with the support and having terminals for engagement with thenotches for maintaining the hangers rigid with relation to the support.

2. The combination withasupport, of hangers carried by the support andmovable toward and from each other, sets of actuating-links disposedrespectively at opposite ends of the support and connected with thehangers, one link of each set having an end projecting above thesupport, and means connected with the projecting ends of the links foroperating the hangers.

3. The combination with asupport, of movable hangers carried by thesupport, sets of links sustained by the support'and connected with therespective hangers, one link in each set having an end projecting abovethe support, and operating-levers connected to the projecting ends ofthe links for operating the latter to actuate the hangers.

1. The combination with a support, of pivoted hangers carried therebyand having side portions provided with notches, seats provided on thehangers for the reception of retainer members, and a plurality ofactuating-links connected with the hanger and support, one of said linksof each set being designed for engagement with the notches in theadjacent hangers to brace the latter relative to the support.

5. A hanger for artificial-stone-making machines having means forengaging a retainerplate, a bar for supporting said hanger, a bracingmember connected to the bar and hanger, and an operating-lever connectedwith the bracing member.

6. A hanger for artificial-stone-making machines having means forengaging a retainerplate, a bar for supporting said hanger, abracing-link connected to the bar and the hanger, and a lever connectedto the bracinglink.

7. The combination with a support having longitudinally-adjustablesections, of pivoted hangers carried by said sections, actuating membersconnected with the sections and hangers, and operating-levers connectedwith the members.

8. The combination with a support, of hangers pivotally connectedtherewith and adapted to swing inward and outward toward and from eachother, means for limiting the inward movement of the hangers, actuatingmembers connected With the latter and the support, operating-leversconnected with the 5 actuating members, and means for locking saidlevers to prevent outward movement of the hangers.
